摘　　要：为了研究梭式止回阀内部的流场特性,采用了数值仿真和对比的方法。利用ADINA软件,分别对梭式止回阀和旋启式止回阀进行流固耦合仿真计算,得出可视化结果,通过对比分析,验证了梭式止回阀在开启过程中具有流速分布均匀,压力分布对称,流动状态稳定,阀芯受力均衡等优势,有利于其研究和推广。To research flow field characteristics of shuttle check valves,this paper adopted numerical simulation and contrast method.Based on ADINA,it respectively implemented fluid-structure interaction calculation on shuttle valve and swing check valve and obtained visualization results.By contrast analysis,it derives that shuttle valves have advantages of uniform velocity distribution,symmetrical pressure distribution,steady flow state,equilibrium load on valve core,etc,beneficial to their research and extension.
